Even though 69% of Americans find texting to be the "most annoying or offensive" activity while driving, 55% admit to using their phone in the car. A new report from Expedia looks at Americans' habits and opinions about driver behavior ahead of the summer travel season.

More than 30 million Americans are likely to travel by car this Memorial Day. The 2014 Road Rage Report, conducted by Northstar, surveyed 1,001 American adults with valid U.S. driver's licenses on their own driving habits and their opinions about other drivers.

"We set out to learn what behaviors on the open road are most welcome, and what behaviors most aggravating," Expedia's Vice President and General Manager John Morrey said in a statement. "The rule, as with airplanes and hotels, is that shared spaces demand decorum and attentiveness.”

The most Americans (69%) identified the "Texter," a driver who texts, emails or talks on the phone while driving, as one of the top five most annoying and offensive behaviors. The "Tailgater" was ranked in the top five worst behaviors by 60% of survey respondents, and the "Multi-tasker" by 54%. Other bad behaviors in the report included hogging the left lane, honking and racing at red lights.

Despite all the annoying things other drivers do, the report found that 56% of Americans "define a road trip as an 'ideal' way to spend a vacation."

Among those surveyed, 70% admitted to aggressive driving behaviors like speeding, tailgating and yelling or swearing at other drivers. "Men are only slightly more likely to admit to aggressive driving than women (74% to 67%)."

But are drivers reticent to admit specific bad behaviors? According to the report, 69% of Americans said they have received the bird from another motorist, but only 17% said they had given it to someone else.
